Explanation

The process by which free electrons are emitted from the metal surface by the application of light is called photoelectric emission.

Explanation

Memory is a process comprised of three stages. 

All information received by our senses goes through these stages:-

1. Encoding: It is the process of converting sensory information into a form that can be processed further by memory systems.
2. Storage: In this second stage, received information from memory systems is stored so that it can be used at a later time also.
3. Retrieval: It refers to locating and bringing the stored material information to one’s awareness when required to complete a task.

Explanation

Objects that are said to be undergoing free fall, are not encountering a significant force of air resistance; they are falling under the sole influence of gravity.

Under such conditions, all objects will fall with the same rate of acceleration, regardless of their mass.

Explanation

Transpiration is the process of removal of excess water from the plants through tiny openings in leaves known as stomata.

Explanation

Fermentation is an anaerobic process in which microorganisms like yeast and bacteria break down food components into other products .

This gives fermented foods their unique and desirable taste, aroma, texture and appearance.

Explanation

• In a parallel circuit, if one bulb blows, the other bulb will remain the same.
• This is because each bulb in a parallel circuit has its own independent path to the power source.
• The failure of one bulb does not affect the current flowing through the other bulb's path.

Explanation

In liquids, particles are quite close together and move with random motion throughout the container.

Particles move rapidly in all directions but collide with each other more frequently than gases due to shorter distances between particles.

With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion.
